【摘要】：目的:评估自制改良的镍钛4种上颌窦剥离器械对山羊平坦上颌窦底黏膜的剥离效果。方法:在建立即时可视的上颌窦底黏膜剥离长度模型的基础上,使用4种上颌窦剥离器械剥离上颌窦底黏膜,对伞形剥离器械组、探针改良型器械组、012镍钛器械组、014镍钛器械组的剥离长度进行方差分析及SNK两两组间比较。结果:4组组间剥离长度差异有统计学意义(P0.01),SNK两两组间比较,4组剥离长度两两之间差异均有统计学意义。结论:对于平坦的上颌窦底,相比较于其他3种剥离器械,镍钛剥离器械表现出明显的优势,2种镍钛剥离器械剥离黏膜的长度均大于伞形剥离器械及探针改良型剥离器械。014镍钛剥离器械剥离上颌窦底黏膜效果优于012镍钛剥离器械。
[Abstract]:Objective: to evaluate the effect of 4 kinds of modified nickel titanium dissection instruments on smooth maxillary sinus floor mucosa in goats.Methods: on the basis of establishing the immediate visual model of maxillary sinus floor mucosa stripping length, four kinds of maxillary sinus dissection instruments were used to peel the maxillary sinus floor mucosa.The peeling length of the modified probe group was analyzed by ANOVA and the comparison of SNK between the two groups.Results there were significant differences in the peeling length between the two groups (P 0.01) and SNK (P 0.01). There were significant differences in the peeling length between the 4 groups.Conclusion: for the flat maxillary sinus floor, compared with the other three kinds of dissection instruments,Nickel-titanium peeling apparatus showed obvious advantages. The length of the two kinds of Ni-Ti peeling instruments was larger than that of umbrella-shaped peeling instruments and the modified nickel-titanium peeling apparatus .014 was better than that of 012 Ni-Ti peeling instruments in removing the maxillary sinus floor mucosa.
